Bleach Your Teeth With Clorox?

Posted on by .

My dentist has this Zoom machine for whitening teeth, but I want to whiten my teeth at home and wondered if it is possible to use Clorox Bleach to do it. I was considering rinsing my teeth with it. Will that work?

Teeth Bleaching Trays

That is interesting. While it could probably whiten your teeth, one thing you should be aware of is that Clorox is a base, such as lye. It’s a rather powerful base at that. This means it can burn living tissue. Believe it or not dentists use it in root canal treatments to do just that.

The active ingredient in household bleach is sodium hypochlorite. This can be used to clean out the organic debris left in a tooth canal all while simultaneously disinfecting it. Rinsing with it regularly inside your mouth is a bad idea because it can burn or damage your gums and inside of your cheeks.

If your goal is to bleach at home, talk to your dentist. There are professional teeth bleaching trays that will allow you to do this. Your dentist will custom-fit them to your bite and provide you with the professional strength whitening gel. You will have all the benefits of at-home whitening without the inherent danger that comes from using Clorox or another household bleach.

I hope this helps.

Can’t I Just Rinse with Peroxide to Whiten My Teeth?

Posted on by .

If the teeth whitening gel is made from peroxide, can I just rinse with the hydrogen peroxide I get at the store? Aren’t they the same thing?

Dear Carl,

teeth bleaching trays

While it is true you could get some mild whitening effect from the peroxide you buy in the store, it will be very mild. There are two reasons for this. First is the strength. The peroxide you get at the store is 3% in strength. The minimum strength you should be getting from professional teeth whitening is 22%. Some are even stronger.

The second issue is absorption. In order for the gel to make any real difference, it would have to stay on your teeth for a minimum of 15 to 20 minutes. That is a long time to try to rinse. It is also the reason dentists will provide you with bleaching trays. You can put the gel in the whitening trays and wear them for as long as is comfortable. The longer you wear them, the more effective they are.

Many patients will wear them overnight because this gives the most bang for their buck. In addition to having them on for many more hours than you would normally tolerate during the day, you also will gain effectiveness. Because your saliva production goes down at night there will be less dilution.

Just remember, no matter what type of teeth whitening you do, it will only whiten your natural tooth structure. If you have any dental work, such as a dental crown, that will stay the same color. After you reach the level of whitening you want, if the dental work is visible, you’ll want to replace the crown. This way your crown can match your new brighter, whiter color.

Expert Tips on Teeth Whitening

Posted on by .

A few years ago, I had my teeth whitened, but they have since picked up more stains. I’m a heavy coffee drinker and knew that would be an issue. Now I need a dental crown on one of my teeth and my dentist wants to schedule me for next week. It’s visible when I smile so I did some research. It seems like it is better to whiten them again before I get the crown placed, but I can’t tell how long I need to get them the right color again. Can you advise me?

Amanda

Dear Amanda,

teeth bleaching trays

While I am going to give you some advice on teeth whitening, I am a little concerned about a couple of things I’m inferring from what you wrote. First, you are having to do this research on your own to figure out what to do. This is unfair to you. Your dentist is supposed to have this training already. He should have advised you that if you wanted to touch up your teeth whitening to do it before getting the dental crown made. One thing we can be grateful for is you figured it out. That’s fantastic! Too many patients don’t and end up having to pay for their crown to be re-done to match the teeth they whiten after the procedure.

A second concern I have is your dentist can’t advise you on the best way to touch up. These two things combined lead me to conclude that he doesn’t have the cosmetic training and skills to do a porcelain crown on your front teeth. These take a lot of skill to not only get to look beautiful, but to blend in with the remainder of your teeth. You may want to ask to see some before and after pictures of cases he’s done similar to yours to see what type of results he gets. If he doesn’t have a smile gallery with photos of his work, then he doesn’t do much cosmetic work and you should see someone else for this procedure.

How Long to Whiten Your Teeth

The basic principle is the longer you can wear your bleaching trays (with the gel in them, of course), the faster your teeth will whiten. The minimum you should leave them in is 15 minutes. The maximum is overnight. While you sleep, your saliva flow goes down which allows the gel to stay in the trays longer, giving you maximum whitening. Some dentists will tell you that you need a special gel made for nighttime whitening, but that isn’t the case. They all contain peroxide. You can wear them during the day as long as you want as well, as long as you are not developing sensitivity.

Once you’ve reached the level of whitening you want, give your teeth a week or two to settle before having the crown made. Oxygen bubbles will still release in your teeth for this amount of time after you stop whitening.
